      <attraccr>Attributes for the military installations database were added using a Geographic Information System (GIS). Attribute values were created by the Surface Deployment and Distribution Command Transportation Engineering Agency (SDDCTEA), and were compiled from unclassified sources such as the "Geolocation File." They have been quality reviewed by both SDDCTEA and the Research and Innovative Technology Administration's Bureau of Transportation Statistics (RITA/BTS).</attraccr>
